Section 13206 Of Article 1. General Provisions From California Elections Code >> Division 13. >> Chapter 3. >> Article 1.

. (a) On the partisan ballot used in a direct primary election, immediately below the instructions to voters, there shall be a box not less than one-half inch high enclosed by a heavy-ruled line the same as the borderline. This box shall be as long as there are columns for the partisan ballot and shall be set directly above these columns. Within the box shall be printed the words "Party-Nominated Offices." Immediately below that phrase within the same box shall be printed the following: "Only voters who disclosed a preference upon registering to vote for the same party as the candidate seeking the nomination of any party for the Presidency or election to a party committee may vote for that candidate at the primary election, unless the party has adopted a rule to permit non-party voters to vote in its primary elections."
  (b) The same style of box described in subdivision (a) shall also appear over the columns of the nonpartisan part of the ballot and within the box in the same style and point size of type shall be printed "Voter-Nominated and Nonpartisan Offices." Immediately below that phrase within the same box shall be printed the following: "All voters, regardless of the party preference they disclosed upon registration, or refusal to disclose a party preference, may vote for any candidate for a voter-nominated or nonpartisan office. The party preference, if any, designated by a candidate for a voter-nominated office is selected by the candidate and is shown for the information of the voters only. It does not imply that the candidate is nominated or endorsed by the party or that the party approves of the candidate. The party preference, if any, of a candidate for a nonpartisan office does not appear on the ballot."
